EFI kit

[Racer x]

I don't know if they have it ready but there is an EFI kit coming for the 250 Ninja.
www.mbe-motorsports.com

[randomwalk101]

$500 is reasonable price. Its plug and play too.

[Jesse8931]

Not sure how well it would work for the 08+ models but for the 07- models there is a guy who makes a kit for racing but he can program it for the street. I will email him and see if it work with the 08+ models

[Anteraan]

I consider this extremely good news. That doesn't mean I'm lining up to get one, but it could certainly up the pressure on Kawi to make the 250 FI, which is what many would like to see.

I've done a search and didn't come across an answer to my question, so if you have an answer or a link to a thread with the answer I'd appreciate it. What are the benefits of EFI compared to our normal US bike?

Benefits of EFI on our bike

• Better MPG and overall performance
• More HP
• Not adversley affected by weather

[gfloyd2002]

I will seriously consider buying one of these.

[Anteraan]

The benefits are generally considered to be among the following:

No rejetting with aftermarket exhaust
No problems at varying altitudes (If I move to Colorado from Indiana...)
Better fuel economy
Better emissions levels
No "cold start" issues

Is it a make or break issue for many riders? No.
Does it create significant improvement for some riders? Yes

if anybody gets it please give out a review, i might get this for my ninja

There's quite a bit of benefits of electronic fuel injection over carburetor. EFI automatically adjusts the fuel/air ratio for you for optimum performance. What this means is that it eliminates the choke and will have no problem cold starting. It'll also be more fuel efficient and can adjust to your environment. With carbs, you are choosing a baseline fuel/air ratio that works best for the majority of your environmental settings (for me, 70's, not much humidity, sea level). When I go up to the mountains where it's thinner air and cooler, I lose performance because of carbs whereas EFI can adjust to the different environmental factors. Biggest thing for people though is easy starts and no more carb cleaning.

So, who will be the first test dummy?? Says it's coming out the 11th

It actually says "This product will be in stock on Monday 18 April, 2011."

I wonder what this will do for the resale value

[Live2ride]

I have a great idea, how about everyone pitches in $25 to get me one, then I'll tell you how well it works.

[HKr1]

Close-loop sounds good. Wonder how much it will adjust off a base map....
When the ecm is adjusting off the map, things kinda run like crap. Gotta have a right map to run on. Long as it comes with nice software to make adjustments, would sound really nice.

i'll give you 25 cents hey that's a start.

i used to ride Buell's and they were fuel injected. having that on the Ninja would be sweet.

[randomwalk101]

I want to see the part list of the kit

[play2pwn]

As soon as it gets a review and DIY Imma get one, lol

[Bo0stZomb13]

This maybe the real first buy for my bike I do.

[J Walk]

Well damn there goes my 10 cents worth of washers wasted

Definitely would love to see someone review once it's available, very interested as well.

[Fly'in Ninja]

Hmmm...interesting If all goes well...group buy!!

How much more power could this motor make? Is it capable of 45-50 hp with efi and significant tuning? Or just not enough displacement?

Haha nothing that dramatic. IIRC, the FI 250's in other countries actually output slightly less hp than our carbed version the way they're mapped.

Ninja 250R HP
EFI= 33
Carb=27

+1

[Racer x]

The factory can claim 33 hp but I did not get that on the dyno without mods. It would be nice if the EFI system will work with aftermarket exhaust. With a closed loop it won't adjust.

Ninja 250R HP
EFI= 33
Carb=27

according to the Kawasaki service manuals...

250R carb= 31.8PS @ 11k/rpm
250R FI = 33PS @ 11k/rpm

[Racer x]

Anyone have a FI bike that has been on the dyno? what is a "ps" At 11 k the stock carb engine makes about 26 hp.

[kkim]

don't know the conversion from ps to bhp, but they are measuring power at the crank and you're quoting rear wheel hp.

my post was to show that carb and EFI bikes turn out very similar peak HP numbers from the factory using the same measuring setup.

PS is a measure of horsepower, used most often in EU, but generally considered obsolete. PS = Pferd Stark, which is German for horsepower. Used most often in advertising, as it slightly inflates values vs. HP. One unit of PS is equivalent to 0.98 horsepower.

I'm tempted to take a collection to get one of these kits for kkim, and let him make a nice DIY for the rest of us to follow.

PS is picosecond, also the German abbreviation for the word Pferdestärke, meaning horsepower.
PS × 0.9863 = HP

I guess it all depends on what country you are in who's dyno you use huh?

[randomwalk101]

Couple hp diff is insignificant. Real adv is no carb clogging, easy start up, no choke, no stall while riding (fuel starves -- FI has fuel pump & vent), etc

[kkim]

the real issue for me is... how would you tune the EFI system? unless someone provides that capability, you're essentially stuck with what you get.

LeoVince Exhaust Systems has ECU for the EFI version 250 Ninjas. These units are installed in the 250 Ninjas for The WSBK European Junior Cup are are programmable. Race-equipped Junior Cup Kawasaki Ninja 250R bikes are also equipped with a full race exhaust and ECU from LeoVince.

okay, but would that work with the system that is the topic of this thread?

Can't be for sure. This EFI kit shows nothing at the moment. If it has software like the Leo Vince, it should be programmable as well. The other EFI conversion kits MBE offers for scooters, advertise as having software and being programmable. Would be a shame if this was anything less.

[kkim]

yes, from what I saw of the kit, I wasn't impressed.

I'm okay with carbs.

+1 for EFI. Honda did it on their U.S. 250 so why can't Kawasaki?

[AMMOCAN]

Maybe it is just me, call me old fashioned or whatever, but I have never experienced EFI on any type of motorcycle wether it be dirt bikes or now on street bikes and I just don't see the reason to spend $500+ on a retro kit to convert my motorcycle to an EFI one. I mean, I never really had an issue with carbs and there doesn't seem to be any significant advantage to justify spending a lot of money on doing this conversion, especially when that type of money could be spent more wisely on other things.

I guess this is just another personal choice to be made, but I honestly can't see why anyone would feel the need to convert their bike except for the simple fact that they have money to blow and want to be one of the few individuals to say that they were one of the first to have the latest and greatest product for the 250R by taking their carburetor motorcycle and convert it to an EFI one.

None of the statements that I have heard and read are substantial enough to justify spending so much money in doing this. I really don't see how this can be an added value to the motorcycle, as by the time you spend the money to purchase the kit and then what ever you end up having to spend on installing it, who knows what the total cost will be. Ok, so lets say you are able to sell the carb to make some of the difference up, but what about the costs of fixing a problem of an EFI system compared to that of a carb problem? In my experience, it has cost a lot more to deal with an EFI problem than it has for a carb problem.

Let's say the EFI system does add a substantial amount of difference in both operation performance and savings, how long would it take before you actually started seeing a positive return in your investment? Again, I think you need to be aware of the costs of fixing a problem if it occurs and what that cost would be if you need to do it yourself or have someone else do it, as sooner or later you will most likely run into an issue, especially considering that you are using a kit that is just coming out.

I have also read and heard that riders who have a stock EFI system have had issues with it when modifying their exhaust and what not. Another issue I would be concerned about is how this conversion would affect those that live in California, as doing the conversion may in some way change the already legal motorcycle to be illegal according to the States current standards. Yes, I know there are many 'California' motorcycles that are EFI and are legal, but it would be interesting to see exactly what extra things would need to be done to make this so with this conversion.

Again, I am simply stating my opinion on the matter and in the end it is a personal choice that I know some if not most of you will make regardless of what anyone has to say. However, I just can't help to wonder what would drive someone to feel the need to pay out so much money in doing this conversion. I am interested to see the outcome of this.
